English: “Male” — male and not female; and why does it say later “a male he shall offer”? To exclude a tumtum and an androgynos.
In the sugya: One zachar would have excluded the female. A second appearance of male language is available for the edge cases — tumtum and androgynos — whose sex is unresolved or dual. The double wording is not waste; it is a second miyut.
Type of Learning
Miyut plus secondary verse for edge cases — male only; tumtum and androgynos out.
What Is Learned
Olah of the herd must be male. Females are out by the first zachar; tumtum and androgynos are out by the reinforced male language. The altar of this unit requires clear male status.
